Imagine never touching another human being... Robert Luxley has a biological problem that he does not understand and cannot control: one touch from his bare skin and you're paralyzed for fifteen minutes. Lonely and isolated, he's turned his "special trick" into a lucrative career as an assassin. He thinks he's one of a kind - until one day he's confronted by a young girl named Cassandra, who tells him that he's not alone. She has it too, and the two of them are not the only carriers of Sensory Deprivation Syndrome (SDS) SDS is a medical condition so dangerous that carriers can render anyone they touch blind or deaf, or otherwise senseless, in seconds. Fearing discovery, Luxley follows Cassandra through a dark underground network of "Deprivers" in a desperate hunt for her missing brother Nicholas, taken hostage by a radical group of carriers with a terrifying agenda. Luxley doesn't know who to trust, or who is safe to touch, but he needs to learn Cassandra's secrets fast. As knowledge of SDS spreads, and panic erupts, no Depriver anywhere in the world will be safe.
